Thanks! Yeah trying to make the background interesting but not overwhelming was really hard to do, luckily you don't have to see the development version which was even messier :D. I'm trying to get away from the outline pixel style slightly and focus on colours so maybe making them contrast and pop a bit more might help?
The difficulty progression had to be pretty fast unfortunately as well since the game is so short but ideally would be more gradual to give time for different players to get comfortable with it. Thanks for playing and giving it a go even though platformers aren't your usual preference and hope you enjoyed it!
